Question

How is winter rainfall of the Northwest part of India different from the winter rainfall of the southeast part of India ?

Answer 1

Winter rainfall or off-monsoon rainfall has two main components. In south, it is called as North east monsoon and in the North west it is called Western Disturbances.

North east monsoon starts in mid-October causing by reversal of trade winds. Trade winds blow from the Siberian high while passing over North Bay of Bengal, picks up moisture and dumps as rainfall over the southern states like Tamil Nadu, Kerala, Andhra Pradesh and Karnataka. Due to the disturbed weather activity over Bay of Bengal, low pressure systems generate and develop in to cyclones which gives most of the rainfall.

However in North west India, post monsoon, dry weather settles down predominantly. At times, low pressure systems form over Mediterranean sea in the west which traverse east. When these weather systems pass over North west India it precipitates as winter rainfall. Western slopes of Himalayas gets most of the rainfall out of this.

Answer 2

Answer:

As explained below.

Explanation:

• Winter rainfall or the off monsoon rainfall is a result of the western disturbances affecting the northern parts of India in winters by bringing a substantial amount of rainfall to the continent. These western disturbances are associated with cloudy sky and higher night temperatures.

• These bring occasionally bring cold wave conditions and dense fogs. Usually, occur from the northern part of Pakistan these disturbances are important for the development of rabi crop that includes locally important staple wheat crop.

• Secondly, the southeastern parts of  India get its winter rainfall in the form of retreating of southwest monsoon winds. In September monsoon winds go back as the development of a low-pressure that forms in the southern hemisphere.

• Due to retreating period wind, direction changes and they start blowing southwestwards. Thus Tamil Nadu coast gets its rainfall, as the winds carry moisture and rainfall takes place on the southern coast of India.
